Disable deinterlace

[Nero]

but I can add support for it, may be there is a scenario where people really use this.

Thank you very much for adding support to it. It's a bit hungry indeed, but in some sources it does a really good job.

I checked my old code and comments, I removed 'none' since it was unnecessary.
The normal intended behavior is:
a. when 'auto' is enabled: Hybrid will deinterlaced if the input isn't progressive and 'Force' is disabled
b. when 'Force' is enabled: Hybrid will always deinterlace depending independent of the scan type

Quite plausible. Thanks for the explanation.
